During the tube high-pressure shearing (t-HPS) process, the traceline of any original radial line segment, with two endpoints located on the inner and outer surfaces of a tubular sample, becomes distorted and elongated. This is an important and intrinsic property of the tangential shear of t-HPS. The new concept of traceline elongation is introduced in order to develop a mathematical description based on the local shear strain. By analogy to the tracelines of interfaces in layered structures, a one-step process is proposed for synthesizing multilayered laminates using t-HPS. It is shown that this process has high efficiency and a low risk of introducing any contaminants. To experimentally verify the feasibility of this proposal, a bimetallic multilayered structure with a micrometer-layer thickness and metallurgical interface-bonding was successfully synthesized using four bulk samples of pure lead and tin as prototype materials.
